ASM cp Command to Remote Disk Group

ASM cp command allows you to copy files between Oracle ASM disk groups and between a disk group and the operating system. Oracle ASM disk groups can be local or remote.

Syntax

cp source_file [rem_connect_str:]target_file

cp [rem_connect_str:]source_file target_file

The rem_connect_str is in the form user@host[.port_number].SID with default port number of 1521. cp cannot copy files between two remote instances. The local Oracle ASM instance must be either the source or the target of the operation.

In an Oracle training material, Oracle New Features for Administrators, the authors stated “the format of the copied files is portable between Little-Endian and Big-Endian systems”. Oracle document (Oracle Automatic Stoarge Management Administrator’s Guide 11g Release 2(11.2), E18951-02) does not address the issue of copying between different endian systems. I tried to copy from Solaris 10 to Linux (see below example) with 11gR2 ASM, but failed with errors.

Example

Local is a Solaris 10 system with 11.2.0.2 ASM instance.

1) copying to another Solaris 10 — Success

ASMCMD>  cp thread_1_seq_4.5135.729122487 sys@sanfords.1521.+ASM1:+recovery/remove.me
Enter password: ******
copying +recovery/testdb2/archivelog/2010_09_07/thread_1_seq_4.5135.729122487 -> sanfords:+recovery/remove.me

2) Copying to Linux (same ASM version) — Failed

ASMCMD> cp thread_1_seq_4.5135.729122487 sys@xh0729.us.oracle.com.1521.+ASM2:+recoverydest/remove.me
Enter password: *******
copying +recovery/testdb2/archivelog/2010_09_07/thread_1_seq_4.5135.729122487 -> xh0729.us.oracle.com:+recoverydest/remove.me
